Scientists and technologists have a social responsibility for the work they do. There is no such thing as science or technology in a social vacuum.

Work and play are not necessarily mutually exclusive.

It is sincerity!
First cultivate sincerity with all your heart
So realize this truth
The World of Reality and the World of Appearance are One
-O Sensei Morihei Ueshiba

Suffering arises from attachment to desires
-Buddha (paraphrase)
